CLOCK CASING.

Application led December 10, 1924. Serial No. 755,05*?.

This invention relates to a clock casing formed of celluloid or similarsheet material and adapted to receive a small cylindrical clockmovement. These casings are formed in various ornamental shapesy and ofdifferent kinds of material and are in very common use for table, deskand other purposes.

It is the object of my invention to improve the mechanical 'constructionof such clocks, producing a clock of more substantial and accuratestructure, and particularly producing a clock in which the clockmovement is accurately centered in the dial opening.

Preferred forms of my invention are shown in the. drawings in Which:

Fig. 1 is a partial rear elevation of a clock casing embodying myimprovements.

Fig. 2 is a horizontal sectional View, taken along the line 22 in Fig.1, and

Fig. 3 is a view similarto Fig. 2, but showing a slightly different formof my invention.

Referring to the drawings, I have shown a clock casing comprisinlg afront frame member 10 having a circular dial opening 11 therein. A.recess 12, (Fig. 2) is formed in the rea-r face of the frame member 10,said recess being circular in outline 'and being accurately centeredwith the dial opening 11.

The movements 13 used in these small clocks are commonly of cylindricalform,

so that they may be held by friction in a movement-supporting sleeve 14.The front end of the sleeve 14 fits accurately in the recess 12 and iscentered thereby, so that the dial of the movement will be accuratelyaligned with the dial opening 11.

The clock casing also comprises a rear portion v15 havinlg a circularopening substantially aligned with the dial opening 11 and with therecess 12 and closely fitting the outside of the movement-sup portingsleeve 14.

In assembling the clock casing, the sleeve 14 is inserted through` therear portion 15 of the casing and is pushed inward until it is seated inthe recess 12 and is accurately centered thereby. The parts are thencemented or otherwise permanently secured in this assembled relation. Inthis way the sleeve 14 is accurately centered as above described andcannot be displaced i.

the fro-nt frame member 17, instead of a recess of the form shown at 12in Fig. 2. In this second form of the invention, the sleeve 14 isengaged by the side walls of the groove 16, both on its inner and outersurfaces, and a larger surface of contact is thus provided for theaction of the cement. Otherwise, the two forms of my invention areidentical and the advantages are as previously described.

Having thus described my invention and the advantages thereof, Ido notwish to be limited to the details herein disclosed otherwise than as setforth in the claims, but what I claim is l. A clock casing formed ofsheet material and comprising a front frame member having a dial openingand having a circular recess formed in the flat rear face. of saidmember, said recess being accurately centered with the dial opening insaid frame member, but having its cylindrical outer shoulder spacedoutwardly from said dial opening, a movement-supporting sleevepermanently secured in position in said casing and centered by saidrecess, and means to support the rear portion of said sleeve.

2. A clock casing formed of sheet material and comprising a front framemember having a dia-l opening and having a circular recess formed in theflat rear face of said member, a rear casing portion having an openingsubstantially aligned with said recess, said recess and rear openingbeing accurately centered with the dial opening, and said recess havingits cylindrical outer shoulder spaced outwardly from said dial opening7and a movementsupporting sleeve extending forward through said rearopening and into said recess to abut said front frame member andpermanently secured in position in said casinlg. l j

3. A clock casing formed of sheet material and comprising e 'front framemember having a. dial opening and having` 2L circular groove formed inthe flat rear face of Said member, accurately centered with said dialopening, but spaced out- Wardly therefrom, a movement-supporting sleeveabutting said frame member and closely tting said groove, said sleevebew ing' secured in said groove and being centered thereby, and means tosupport the rear portion of Said sleeve.

In testimony whereof I have hereunto aixed my Signature.
